Vantage signs over 1 GW solid-state transformer capacity deal with Heron Power for 800 VDC AI data centers
Vantage and power-electronics maker Heron Power announced a GW-scale manufacturing capacity agreement under which Vantage will secure more than 1 GW of Heron Link solid-state transformer capacity, according to TechNews. Vantage plans to deploy the equipment in its hyperscale data center campuses, converting medium-voltage grid power directly to 800 VDC instead of the traditional 480 V AC architecture. Heron says Heron Link also integrates energy storage and targets conversion efficiency above 98.5%, though no independent measurements were provided.
The deal is a concrete supply commitment for 800 VDC power architecture, which the report links to rising AI rack power density, and Heron is listed as a participant in Nvidia's 800 VDC MGX ecosystem.
800 VDC 供電架構加速邁向實際部署。全球資料中心業者 Vantage 與電力電子設備商 Heron Power 宣布簽署 GW 級製造產能合作協議，Vantage 將取得超過 1 GW 的 Heron Link 固態變壓器（SST）製造產能，規劃導入旗下超大規模資料中心園區，透過中壓電力直接轉換為 800 VDC，簡化供電架構，目標能源轉換效率超過 98.5%。
隨著 AI 伺服器運算能力持續提升，機櫃功率密度逐漸朝 MW 等級發展，資料中心面臨電力供應、設備交期及建置成本等挑戰。傳統資料中心多採用 480 V 交流電架構，電力從電網輸送至伺服器機櫃前，須經過多個電壓轉換及配電階段，不僅增加設備需求，也提高能源損耗與系統建置複雜度。
